Cell phone video from the scene appears to show a man pointing a rifle at protesters as they move across the street towards a group of pro-Trump supporters, leading to scuffles.

“Alright everybody, back the f— up,” he yells.

He was arrested and booked.

According to police, the crowd was ordered to disperse after blocking the street and violating the curfew orders which began at 6 p.m.

Some protesters left, but those that remained turned violent, police said, with rocks and water bottles thrown at officers, prompting them to deploy pepper balls and sting balls to push the crowd back.

No one else was arrested, however, and the crowd eventually scattered.
